Within this interconnected ecosystem, the costs of cybercrimes could exceed $15 trillion by 2027. Businesses have responded by investing in cybersecurity measures, keeping the global cybersecurity market on pace to reach over $500 billion by 2030. Cybersecurity is thriving on this concentration of capital, and public cybersecurity companies provide a way in for the average investor. 

In contrast to private companies, publicly traded cybersecurity companies allow anyone to own shares in the company and earn some of the profits. And because they can more easily access funds from larger investor pools, these businesses must abide by strict SEC regulations. This way, public companies can quickly fund new projects and growth initiatives while maintaining trust with investors and financial authorities. 

Fast funding will be necessary to keep up with the field, which has already incorporated technologies like artificial intelligence and machine learning to accelerate processes. Investors may then want to gain an early foothold in the industry before it takes off in the coming years.   

With that in mind, we’ve gathered a list of publicly traded cybersecurity companies you should know.
